Vibraplane vs. Minus k for Turntables

Larry,

All the Minus K vibration isolators have leveling feet. I don't know about the work stations as I never considered purchasing one. They are, however, very robust and will no doubt provide you with a stand second to none with regard to rigidity.

I'll be fabricating a welded tubular steel stand for my table. I want the platter chest high for ease of use. I also need the stand to accommodate the vacuum pump for the platter along with 3 Krell KPE Rerference head amps with the separate power supplies, one for each of the 3 arm-cartridge combos on the table. Since the KPE units only have single ended outputs, it would have been necessary for me to locate the table next to the processor - preamp, something I didn't want to do. The turntable will be across the room from the processor so I have a Krell KCT pre amp directly under the KPEs acting as a selector - preamp that will send the signal via balanced lines to the processor. Since the KCT also has CAST outputs I can use them sometime in the future when I upgrade my HTS 7.1 The remote controlled KCT will also enable me to make direct comparisons among the 3 cartridges as they all track the same groove. Lots of stuff on the stand, it's good the room is on a slab.

Good luck with your TERES project.

Any updates on the Minus K or Halcyonics platforms?.

I have a similar problem to Dgad, except that nothing happens to my needle, just a low frequency feedback sound if I stamp down close to the turntables.

I might go Dgad's much cheaper route, as I would need to go BM-1 size with the Raven AC-3.

I had never heard of Minus K, until this thread. So thanks for putting it up. I just went to the Minus K website to check out their prices and specs. Seems like the BM8, which costs less than $3K, would be a good choice for most tt's, which tend to weigh less than the 105-lb upper limit of this model. Plus, the level of isolation is only a hair's breath less good (f=1.5Hz vs 0.5Hz) than their top model. Has anyone tried the BM8? Thanks.

Whoops! I see above that sdlevine is an owner of a BM8 and likes it. Moreover, I erred in reporting the performance of the BM8, which is f = 0.5Hz in the vertical plane, as sdlevine says. I will have to struggle with my conscience over purchasing one of these, maybe sell an extra turntable to pay for it.

I have been using a Minus K for over two years now. Mine is a custom BM-8, and it will support the Raven AC-3's weight and size.
The advantage to BM-8 over the BM-1 is the lower center of gravity, reduced height and looks.

Zero maintenance, once setup you can forget about it. You can jump up and down next to it and it will keep on playing cleanly.
